• Progressing past CRUD applications in PHP?

  - by Anonymous -

  I've been programming in PHP for about a year and am at the following stage: Have a good 'feel' for the language Can create CRUD applications competently Can utilize an MVC structure to allow for future expansion of code Using the points listed above, I've created a number of my own applications for practise - including but not limited to; a forum, social network etc. My question may be a little vague but should hopefully be answerable. I feel as though there isn't anything else I would need to know about PHP to allow me to create websites, though I'm sure I'm wrong. What advanced/complex PHP topics could I look at that have a real-world use and will allow me to enhance both my skill as a programmer and applications in general? Recently I've looked a lot more at javascript/jQuery allowing me to give my applications a richer user interface which has been a great learning experience and proving very useful.

• Using Git in Enterprise environment

  - by sarat

  Git is an excellent version control. If we exclude the fact that, it doesn't have an excellent GUI support, it's really good and fast. But the source controls like Clearcase has large support for enterprise customers. Companies investing huge amount for source control servers and licesense. Of late most of the large companies like Google adopting Git over the other version controls. But the company is having strong open source group which consistently provide development and support for the tool (Even they might be having a custom version of Git of their own). At the same time, large companies are not really bothered about adopting open source projects and make it relevant for them. Is Git really a reliable tool for enterprise environment, especially for Windows Platform? The support is a question for Git as it's an open source version control. Any companies are there to provide solutions and support? How the server costs comparing to other version controls like Clear-case?

• Is it necessary to understand what's happening at the hardware level to be a good programmer?

  - by bev

  I'm a self-taught programmer, just in case this question is answered in CS 101. I've learned and used lots of languages, mostly for my own personal use, but occasionally for professional stuff. It seems that I'm always running into the same wall when I run into trouble programming. For example, I just asked a question on another forum about how to handle a pointer-to-array that was returned by a function. Initially I'm thinking that I simply don't know the proper technique that the designers of C++ set up to handle the situation. But from the answers and discussions that follow I see that I don't really get what happens when something is 'returned'. How deep a level of understanding of the programming process must a good programmer achieve?

• How to change time servers in 11.10

  - by Reinis I.

  I'm behind NAT, so I can't access pool.ntp.org or Ubuntu's own time servers directly, and I'd like to change the time servers for my system. When googling, I find references to missing manpages like ntpd.conf(5) and ntpd(8), to a missing GUI for setting the time servers, and to a cron script (/etc/cron.daily/ntpdate) that doesn't seem to exist on my system. I've also found a reference to there being changes to ntpd.conf, so I'm hesitant to just create that file in /etc. How is one supposed to change the time servers in 11.10?

• Legality of modifying and distributing the JRE

  - by herpylderp

  I see that Google App Engine apps run on a so-called secured sandbox JRE; that is, a JRE that Google modified and that makes changes to certain JRE types. This is how GAE prevents developers from writing apps that can do things like: Access the local file system via File Make remote JDBC calls Use JNDI Lots of other restrictions We have a similar need where we have an app that developers will be able to write plugins for. These plugins will need to utilize an API (a JAR) that we distribute with our app. We cannot afford for plugins to do certain things, particularly on the end user's file system, and need to modify the File class in a similar manner that GAE does. Long back-story short, this means we'll need to ship our app with a custom, modified JRE. My question: is this legal to do, or did Google likely pay Oracle some fee to modify/distribute their own JRE for app engine?

• Does facebook store multiple password hashes for each user?

  - by loxxy

  I noticed that Facebook allows multiple variants of my own password : My password as it is. My password with first letter capitalized. My password with all letters capitalized. It is commonly known that passwords are stored as hashes. So my question is, does facebook store multiple hashes for each user? Since the hash of each variant should be completely different... Or am I missing something, here? And there may be more combinations, besides the one I observed as well. This is obviously done to provide a better user experience & they probably have a statistical explanation of people repeating these mistakes. But I could not help but wonder, is it worth to increase so many lookups (in their database) just to help the user type a wrong password? On top of this, they warn about the caps lock (even though they don't seem to care) :

• Free Windows 8 book on programming with html, css and javascript

  - by Dave Noderer

  Just a heads up from DevFish (http://devfish.net), a free book on writing applications for Windows 8using html, css and javascript by Kraig Brockschmidt . You can find the book here: http://blogs.msdn.com/b/microsoft_press/archive/2012/10/29/free-ebook-programming-windows-8-apps-with-html-css-and-javascript.aspx I have not finished reading this but so far it looks like it will be a great resource if you have any interest in trying the windows 8 javascript programming model. Besides all the aspects of controls, library support and animations the book also talks about how to make your own components in c#, vb or c++.

• Reduced Tree View in NetBeans IDE 7.2

  - by Geertjan

  Right-click within the Projects window in NetBeans IDE 7.2 and from the "View Java Packages As" menu, you can now choose "Reduced Tree".I never really understood the difference between "Reduced Tree" and the already existing "Tree". But it makes sense when you see it. Here's Reduced Tree view: And here's Tree view, where you can see that the "actions" and "nodes" packages above each have their own top level package nodes, which takes up more space than the above: What's cool is that your selected package view is persisted across restarts of the IDE. To be complete, here's the List view, which is the third option you have in the "View Java Packages As" menu: Seems to me like the new Reduced Tree view combines the best of the Tree view with the best of the List view! Related issue: http://netbeans.org/bugzilla/show_bug.cgi?id=53192

• What soft can create deb repository with several versions of the same package?

  - by bessarabov

  I want to create my own deb repository to store some packages. I've tried reprepro and it works fine, except one but fundamental feature. Reprepro can't store several versions of the same package in the repository. But the ability to store several versions of the same package is essential to me, so I'm asking what soft can do such a thing. Here is a piece of reprepro FAQ that shows that it can't do it: 3.1) Can I have two versions of a package in the same distribution? ------------------------------------------------------------------- Sorry, this is not possible right now, as reprepro heavily optimizes at only having one version of a package in a suite-type-component-architecture quadruple. You can have different versions in different architectures and/or components within the same suite. (Even different versions of a architecture all package in different architectures of the same suite). But within the same architecture and the same component of a distribution it is not possible.

• What is an achievable way of setting content budgets (e.g. polygon count) for level content in a 3D title?

  - by MrCranky

  In answering this question for swquinn, the answer raised a more pertinent question that I'd like to hear answers to. I'll post our own strategy (promise I won't accept it as the answer), but I'd like to hear others. Specifically: how do you go about setting a sensible budget for your content team. Usually one of the very first questions asked in a development is: what's our polygon budget? Of course, these days it's rare that vertex/poly count alone is the limiting factor, instead shader complexity, fill-rate, lighting complexity, all come into play. What the content team want are some hard numbers / limits to work to such that they have a reasonable expectation that their content, once it actually gets into the engine, will not be too heavy. Given that 'it depends' isn't a particularly useful answer, I'd like to hear a strategy that allows me to give them workable limits without being a) misleading, or b) wrong.

• Improving FAQ SEO with multiple pages?

  - by asdfasdf

  I have a client who has over 200 Question/Answer style content blocks. Neither the questions or answers are very long and most of them have almost the same question but with a word or two differentiating themselves from the rest of the questions. Would SEO be helped or hurt if I would to put each QA on its own page with the title of the page the question being asked etc... Or, would that be considered "farming"? If not, what would be the best way (in SEO world) do present all these QAs? Thanks for any advice..

• Is it the job of a developer to suggest IT requirements?

  - by anything

  I am the only developer working on a web application which is nearing to its end. Now we are looking into making it Live in maybe a couple of months time. This is a web application for a non IT company. Though they have their own internal IT team, they have asked me on what will be the hardware requirements for the live servers eg. RAM, 32 bit or 64 bit. Shouldn't the internal IT team be doing this or since I am the only person working on the project is it my resposiblity to let them know of the any specific hardware requiremnts which may impact the performance of the project? The reason I am asking this question is that, I have not this before. All the times I used to be given a server and asked to deploy apps on it. I never used to worry about the server configuration etc.

• New Java EE 6 Hands-On lab, Devoxx-approved!

  - by alexismp

  A new Java EE 6 HOL (Hands-On Lab) was successfully used yesterday at Devoxx with a room packed with enthusiast conference participants. This is new material which covers a lot of Java EE ground in a single document. As it is the case for most GlassFish-related labs, the list of software requirements is dead-simple and short: a recent JDK (6 or 7) and NetBeans 7.x ("Java EE" or "All") which comes with GlassFish. Of course GlassFish can also be downloaded separately and used from other IDEs such as Eclipse and IntelliJ or even (Emacs). The didactic nature of the HOL document should make it useful for anyone interested in learning Java EE 6 on their own time and pace. If you have feedback about the content or about GlassFish, make sure you voice your concerns (or praises) to the GlassFish Users alias as indicated in the document. Feedback will be taken into account in the form of updates to the document as well as enhancements to GlassFish (ideally in 3.1.2).

• Wireless will not work in fresh ubuntu 12.04 lts installation

  - by Taake Manning

  I did a fresh Ubuntu 12.04 install on my Sony Vaio laptop, which worked perfectly with 10.04. Now my wireless won't work. I have read just about every Q&A on the subject and I have tried different solutions, including the official troubleshooting guides. My laptop is equipped with a Intel 5100 wireless device. Ubuntu recognizes the device and it's status is given as connected in nm-tool. I can ping the gateway, my own IP number and localhost. Rfkill shows no soft or hard blocks. Any ideas? I am just a few hours shy of reinstalling good old 10.04! Taake

• Even distribution through a chain of resources

  - by ClosetGeek

  I'm working on an algorithm which routes tasks through a chain of distributed resources based on a hash (or random number). For example, say you have 10 gateways into a service which distribute tasks to 1000 handlers through 100 queues. 10,000 connected clients are expected to be connected to gateways at any given time (numbers are very general to keep it simple). Thats 10,000 clients 10 gateways (producers) 100 queues 1000 workers/handlers (consumers) The flow of each task is client-gateway-queue-worker Each client will have it's own hash/number which is used to route each task from the client to the same worker each time, with each task going through the same gateway and queue each time. Yet the algorithm handles distribution evenly, meaning each gateway, queue, and worker will have an even workload. My question is what exactly would this be called? Does such a thing already exist? This started off as a DHT, but I realized that DHTs can't do exactly what I need, so I started from scratch.

• What Design Pattern is separating transform converters

  - by RevMoon

  For converting a Java object model into XML I am using the following design: For different types of objects (e.g. primitive types, collections, null, etc.) I define each its own converter, which acts appropriate with respect to the given type. This way it can easily extended without adding code to a huge if-else-then construct. The converters are chosen by a method which tests whether the object is convertable at all and by using a priority ordering. The priority ordering is important so let's say a List is not converted by the POJO converter, even though it is convertable as such it would be more appropriate to use the collection converter. What design pattern is that? I can only think of a similarity to the command pattern.

• Is it safe to run multiple XNA ContentManager instances on multiple threads?

  - by Boinst

  My XNA project currently uses one ContentManager instance, and one dedicated background thread for loading all content. I wonder, would it be safe to have multiple ContentManager instances, each in it's own dedicated thread, loading different content at the same time? I'm prompted to ask this question because this article makes the following statement: If there are two textures created at the same time on different threads, they will clobber the other and you will end up with some garbage in the textures. I think that what the author is saying here, is that if I access one ContentManager simultaneously on two threads, I'll get garbage. But what if I have separate ContentManager instances for each thread? If no-one knows the answer already from experience, I'll go ahead and try it and see what happens.

• Remove "computer" and "network" categories from Nautilus sidebar (ubuntu 12.04 running Cinnamon 1.4)

  - by utnubu_user

  I am wondering if it is possibly to completely remove the "computer" and "network" categories from Nautilus sidebar. I would like to do this because the locations that fall under them cannot be edited and I don't use those. Instead, I prefer to specify my own locations which I can do through the Bookmarks. This is all fine, but the "computer" and "network" just sit there doing nothing (potentially distracting). It seems these categories are hardcoded in Nautilus 3.4.2? At least I can't find a way to remove them. Any suggestions are welcomed.

• Is it possible to boot Ubuntu using the Windows bootloader?

  - by badp

  As noted by many people, Windows 8's UEFI requirements might will won't get in the way of installing Linux (or whatever), as the replacement bootloader will also need to be signed somehow. Some systems All systems will let you disable the signature requirement, but the feature might be hidden to disable or you might not be willing to give up on the benefits of a secure bootloader. Is it necessary to replace the bootloader in the first place? To keep ourselves to software that's gone golden, how can I install Ubuntu 11.04 using Windows 7's own bootloader?

• STL for games, yea or nay?

  - by munificent

  Every programming language has its standard library of containers, algorithms, and other helpful stuff. With languages like C#, Java, and Python, it's practically inconceivable to use the language without its standard lib. Yet, on many C++ games I've worked on, we either didn't use the STL at all, used a tiny fraction of it, or used our own implementation. It's hard to tell if that was a sound decision for our games, or one simply made out of ignorance of the STL. So... is the STL a good fit or not?

• /build folder used by PEAR

  - by Paul

  I've just noticed a root directory (/build) which I can't seem to find any information for. It looks like it's some sort of staging ground for PEAR (PHP). There are only two folders of different php versions in it, and each of those has a few PEAR tar files I've installed (via the PEAR command line). I'm really only asking this question because I find is strange PEAR (and only PEAR) would create its own root directory to store files. Is this normal? Does Ubuntu provide a /build directory for applications to use?

• Which language unifies OOP, both RPC call and Message passing a la Smalltalk, and more ...

  - by user310291

  I hate software editors who pretend to know better what you need and choose for you. Java and c# pretend multiple inheritance is dangerous. That I agree I often use Interface but in some cases I may need multiple inheritance : why not let me choose ? Also today you have to choose between RPC call à la Java and Message passing à la Objective C. Again can't I choose when one or the other is more practical ? So is there any language on earth which will free me from what I want to choose to use dependending on MY context and MY own judgement ?
